舌感受器的比较组织学观察
0
()
摘要:
本文用比较组织学方法,观察大量舌组织切片,初步发现:舌感受器随着动物进化发展在种类与形态结构上有较明显的差异,两栖类最为简单,只看到游离神经末梢;啮齿、偶蹄和食肉类较复杂,有游离神经末梢、丛束状神经末梢、味蕾和肌梭等;人类最为高级,结构最为复杂,增加了肌间结缔组织感受器、肌束膜感受器、血管旁感受器和肌腱感受器等。此外,本文还对上述感受器进行了生理机能、组织发生和生物进化方面的分析和讨论。

AN OBSERVATION OF COMPARATIVE HISTOLOGY OF RECEPTOR OF TOUGUE
()
Abstract:
The article descibes an observation of the tongue receptors of frog, toad, rabbit, albino rat, pig, dog, and human beingin terms of comparative histology, through the study of morphologie structure and animal kind, clear differentiations were found at different stages of evolution:(1) the amphibians have the simplestglossalrecePtors; (2) therodents, the artiodactyls and the carnivores have comparatively complex glossal receptors; (3) the human being has the most advanced glossal receptors.
Key words:  Receptor,Nerve endings,Serial sections,Fixation,Staning,Paraffin wrapping(wrappage),
